39751970, Aug 17, 1976
Filed:
Jan 6, 1975
Appl. No.:
5/538928
Inventors:
Valdis Mikelsons - Mendota Heights MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
B41N 108
C23F 706
US Classification:
96 86R
Abstract:
Aluminum substrates are provided having a coating of particulate material bound thereto by means of an in situ formed binder of aluminum hydroxyoxide. The coated aluminum constructions have utility in imaging and reproduction processes (e. g. , as printing plates, as electrographic elements, etc. ), as magnetic recording surfaces, controlled roughness surfaces, decorative panels, protective surfaces, etc.

Process For Preparing Liquid Toners With Hydrocarbon Solvents

View page
US Patent:
57537631, May 19, 1998
Filed:
Oct 30, 1996
Appl. No.:
8/739977
Inventors:
Prabhakara S. Rao - Maplewood MN
Valdis Mikelsons - Mendota Heights MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
C08F25900
US Classification:
525276
Abstract:
The toner particles of this invention comprise pigment and a resin. The resin comprises a novel polymer formed from ethylenically unsaturated monomers, macromeric moieties that render the resin dispersible in hydrocarbon solvents, and a surface-release promoting moiety. When used for toner particles the polymer further comprises charge directing chelating moieties. The toner particles also include a charge director, preferably a metal cation. The toner particles, when dispersed in a carrier liquid, are useful as liquid toners for electrographic or electrophotographic processes.

Method And Apparatus Having Improved Image Transfer Characteristics For Producing An Image On A Receptor Medium Such As A Plain Paper

US Patent:
56502532, Jul 22, 1997
Filed:
Sep 29, 1995
Appl. No.:
8/536687
Inventors:
James A. Baker - Hudson WI
Truman F. Kellie - Lakeland MN
Edward J. Woo - Woodbury MN
Kent E. Emerson - South St. Paul MN
Wu-Shyong Li - Woodbury WA
Gaye K. Lehman - St. Paul MN
Gay L. Herman - Cottage Grove MN

Valdis Mikelsons - Mendota Heights MN
Assignee:
Minnesota Mining and Manufacturing Company - Saint Paul MN
International Classification:
G03G 1311
US Classification:
430119
Abstract:
Method and apparatus for producing an image on plain paper from image data using a photoreceptor. An image-wise distribution of charges is produced on the photoreceptor corresponding to the image data. A liquid ink having solid charged pigmented particles, the liquid ink having an effective glass transition temperature of less than 25 degrees Celsius is applied to the photoreceptor forming an image-wise distribution of the pigmented particles on the photoreceptor to form the image. The liquid ink has greater than seventy-five percent by volume fraction of solids in the image. A film forming means is positioned against the photoreceptor immediately following the application means to dry the image of the liquid ink to film forming within 0. 5 seconds. The image is dried on the photoreceptor. The image is then transferred to an elastomeric transfer roller which forms a first transfer nip under pressure with the photoreceptor.

Radiation Absorbing Surfaces

View page
US Patent:
45821119, Apr 15, 1986
Filed:
Mar 10, 1983
Appl. No.:
6/474716
Inventors:
Robert D. Kuehn - Eagan MN
Valdis Mikelsons - Mendota MN
Gary L. Dorer - Taunton MA
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
B22D 2300
US Classification:
164 46
Abstract:
A substantially radiation absorbing layer of metal having a microstructured surface characterized by a plurality of randomly positioned discrete protuberances of varying heights and shapes, which protuberances have a height of not less than 20 nanometers nor more than 1500 nm, and the bases of which contact the bases of substantially all adjacent protuberances is disclosed. The metal layer, which may be a coating on a variety of substrates, is useful as a radiation absorber (particularly solar). A method is disclosed for producing such layers.

US Patent:
52622592, Nov 16, 1993
Filed:
Apr 18, 1990
Appl. No.:
7/510597
Inventors:
Hsin-hsin Chou - Woodbury MN
John F. Eisele - Lakeland MN
Gaye K. Lehman - St. Paul MN
Wu-Shyong Li - Woodbury MN
Valdis Mikelsons - Mendota Heights MN

Paul J. Wang - Woodbury MN
Gregory L. Zwaldo - Ellsworth WI
Michael G. Baier - Maplewood MN
Richard H. Olson - St. Paul MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
G03G 1314
G03G 2100
US Classification:
430 47
Abstract:
An electrographic imaging process is described in which electrostatic images are toned in sequence to form a multicolor intermediate image on a temporary dielectric receptor. The intermediate image is then transferred to a permanent receptor. Certain relative properties of the toner and the intermediate image, such as surface energy, T. sub. g, work of adhesion, and complex dynamic viscosity, have been found to be important to the production of good final images.
